Figure 2From: Low-dose endotoxin inhalation in healthy volunteers - a challenge model for early clinical drug development Procedures performed on challenge days LPS 1, LPS 2 and LPS Tx (Figure 1 ). FEV1 = lung function measurement, EBT = exhaled breath temperature, BT = body temperature, LPS = low dose lipopolysaccharide challenge (20,000 E.U.), 1 blood samples were not taken at visit 3 (LPS1). Lung function was also monitored by a portable AM1 detector hourly for 6 h, as well as 9, 11, 13, and 24 h after LPS challenge. Lung function results and the subject’s symptoms at 24 h were assessed by phone call.Back to article page
